Using this Deejo knife is a breeze. Simply use the liner lock to open and close the blade safely. When you're done, you can easily clip it to your belt using the belt clip for quick access. As for maintenance, after each use, wipe the blade clean with a dry cloth to prevent rust. Avoid using it for heavy - duty tasks that might damage the delicate blade. Store it in a dry place to keep the juniper handle in good condition. If the handle loses its natural fragrance over time, you can gently sand it to bring out the aroma again.
